TTL in DNS and Networking: Key Concepts

When discussing networking and the Domain Name System (DNS), one of the most critical yet often overlooked parameters is the Time to Live (TTL).

You have to be prepared to handle big traffic loads. Otherwise, your current system can be easily saturated and crashed.

Does it sound hard? Well, there are different technologies and strategies you can use. Today, we will talk about Round Robin DNS.

Round Robin DNS: Definition

Round Robin DNS is a DNS solution to distribute the traffic among different servers. It allows the redirection of traffic to other servers to prevent stress points and overloads for your servers. If you are familiar with the concept of load balancing, well, this is one option to do it.

Why do you need Round-Robin DNS?
